Authorities said Stephen Dillard was killed by his former foster child, Ronshai Jenefor, 21.

Aynn Dillard said she wants her brother to be remembered by how he lived, not by how he died.

She said his life was about helping children, and it's a shame his life work is now over.

"Steve spent his life dedicated to trying to improve the lives of some of Louisville's disadvantaged and forgotten children, many of whom are from Louisville's most violent neighborhoods," said Aynn Dillard.

Stephen Dillard opened up his home to children in need. He was a foster parent, a mentor and a teacher in Jefferson County, who most recently worked at Carrithers Middle School.

He was also known for his love of chess.

Stephen Dillard was found Friday morning beaten and stabbed to death.

Police found Jenefor not far from the scene covered in blood. Jenefor is now charged with murder.

"He did not give a motive. He did confess to the crime," said Jeffersontown Police Maj. Kenneth Hatmaker.

"We would like to thank the Jeffersontown Police Department that responded in Friday," Aynn Dillard said. "They made an intolerable (situation) bearable."

Aynn Dillard said her family is now making funeral arrangements, and she spoke out to other families who are also going through tragedy.

"We were not the only family touched by tragedy his past week, and our hearts go out to the other families who are mourning the loss of their loved ones," Aynn Dillard said.
